Course Description
PSY3215 is a research methods course in psychology. The Statewide Course Numbering System titles it Principles of Research Methodology (Cont) — ⚠ note the "(Cont)", which is doing real work — and describes it as the "design, analysis and interpretation of complex research projects in psychology." The state also flags it as a laboratory course. There is no statewide prerequisite listed.
⚠⚠⚠ Three separate things about this number need to be understood before you register, and together they make it one of the more confused identifiers in this catalog.
| Institution | Its title | Credits |
|---|
| Florida International University | Research Methods and Data Analysis in Psychology | 4 |
| University of West Florida | Research Methods in Psychological Science | 3 |
1. ⚠⚠ The statewide "(Cont)" marker says this is a SECOND methods course — and UWF's title does not. A continuation implies a first course before it. UWF's "Research Methods in Psychological Science" reads like a first, standalone methods course. ⚠ So this number may be the first methods course at one institution and the second at another, which changes what it assumes you already know.
2. ⚠⚠⚠ FIU's title is the statewide title of a DIFFERENT number. Florida numbers `PSY3211` "Research Methods and Data Analysis in Psychology" — exactly FIU's title — as its own course, with a statistics prerequisite. So FIU appears to be running under `PSY3215` a course the state numbers `PSY3211`.
3. ⚠ The credits diverge 3 versus 4, and FIU's extra credit is explained by its title: data analysis folded in alongside methods.
⚠ Whatever the packaging, the subject is not in doubt and the content is the most important thing a psychology major learns. Research methods is where a student stops consuming psychological claims and starts being able to evaluate them: what design supports what inference, what a confound does, why a correlation is not a cause, what a p-value does and does not mean, and why a great deal of published psychology has failed to replicate. ⚠⚠ It is also, by a wide margin, the course that most determines whether a psychology graduate is employable in anything analytical.
Learning Outcomes
Required Outcomes
- Distinguish the major research designs — experimental, quasi-experimental, correlational, observational, single-case, longitudinal, cross-sectional — and state what each can and cannot support.
- ⚠ Formulate a testable hypothesis from a theory, and specify the prediction precisely enough to be wrong.
- Apply operational definition and assess reliability and validity — internal, external, construct, statistical-conclusion.
- ⚠⚠ Identify confounds and threats to validity, and design against them: randomisation, counterbalancing, control conditions, blinding, matching.
- Design and analyse factorial experiments, and interpret main effects and interactions — ⚠ the "complex research projects" the statewide description names.
- Distinguish between-subjects, within-subjects and mixed designs and explain the trade-offs of each.
- Select and apply the appropriate inferential test — t-tests, one- and two-way ANOVA, repeated-measures ANOVA, correlation, regression, chi-square — and state its assumptions.
- ⚠ Interpret effect sizes and confidence intervals, and explain why they matter more than a significance verdict.
- Explain statistical power and conduct or interpret a power analysis to choose a sample size.
- ⚠⚠ Explain what a p-value is and is not, and identify p-hacking, HARKing, selective reporting and researcher degrees of freedom.
- ⚠ Explain the replication crisis in psychology, its causes, and the reforms responding to it — preregistration, registered reports, open data, larger samples.
- Apply sampling concepts, and assess the generalisability of a sample; ⚠ explain the WEIRD-sample problem.
- Use statistical software — SPSS, R or jamovi — to run and interpret analyses.
- ⚠⚠ Apply research ethics: informed consent, deception and debriefing, confidentiality, vulnerable populations, the IRB process, and the historical abuses that produced the rules.
- Read a primary research article critically — method, analysis, and whether the conclusion is supported.
- ⚠ Write in APA style to publication conventions, including results reported correctly.
- Design, conduct, analyse and report an original empirical study — normally the course's central work.
Optional Outcomes
- Apply advanced designs — mixed models, mediation and moderation, multiple regression, factor analysis in outline.
- Apply qualitative methods — interviews, thematic analysis — and mixed-methods designs.
- Apply psychometrics — scale construction, item analysis, reliability estimation.
- Apply meta-analysis in outline, and read a forest plot.
- ⚠ Preregister a study and publish materials on a public repository.
- Conduct an online study — Qualtrics, Prolific, MTurk — and address the data-quality problems that come with it.
- Apply Bayesian approaches in outline.
- Present at an undergraduate research conference or submit to a student journal.
- Use R and reproducible workflows (R Markdown, version control).
Major Topics
Required Topics
- Science and psychology — falsifiability, theory and hypothesis, the difference between a scientific and a non-scientific claim.
- Measurement — operational definitions, scales of measurement, reliability, validity.

- Quasi-experimental and correlational designs — and what can be inferred from each.
- Sampling and generalisability, including the WEIRD problem.
- Inferential statistics in practice — t-tests, ANOVA, correlation, regression, chi-square; assumptions and violations.
- ⚠⚠ Effect size, confidence intervals and power — and why a significant result from a small sample is weak evidence.

- Conference presentation and publication.
Resources & Tools
- Research Methods in Psychology by Shaughnessy, Zechmeister and Zechmeister, and Cozby and Bates' Methods in Behavioral Research, are the two most widely adopted texts. Research Design and Statistical Analysis (Myers, Well and Lorch) is the more rigorous option where methods and statistics are combined — ⚠ likely at FIU, given its title.
- ⚠⚠ Free and genuinely as good as a paid text: Research Methods in Psychology (Price, Jhangiani and Chiang) — an open textbook, complete and well written; Learning Statistics with R by Danielle Navarro (free, and unusually humane about statistics); and the Open Science Framework (osf.io) for preregistration and materials, which is free and is where the field is going.
- ⚠⚠ Software, and the choice matters for your employability: SPSS is still common in psychology teaching and is licensed by most institutions. ⚠ But R and jamovi are FREE, and R is what research and data-analysis jobs actually use. jamovi is free, looks like SPSS and runs on R — ⚠ the best bridge available if your course teaches SPSS and you want a transferable skill. G*Power is free for power analysis.
- ⚠ The APA Publication Manual (7th edition) — and the free APA Style website and Purdue OWL cover almost everything an undergraduate needs. ⚠ Learn to report a result correctly — statistic, degrees of freedom, value, p, and effect size — because it is graded and it is a professional habit.
- ⚠ On the replication crisis, the primary sources are free and short enough to read: the Open Science Collaboration's 2015 Estimating the reproducibility of psychological science, Simmons, Nelson and Simonsohn's "False-Positive Psychology", and Ioannidis's "Why Most Published Research Findings Are False." ⚠⚠ These three papers changed the field and are more instructive than any textbook chapter about them.
- ⚠ Your institution's IRB and its student-research procedure, plus CITI training, which many programmes require before data collection. ⚠⚠ Ask in week one how long IRB approval takes at your institution — it is the most common reason a course project runs out of term.
- ⚠ Florida context: the state universities run participant pools (usually introductory psychology students earning course credit) that make undergraduate data collection feasible — ask how yours works and what its rules are. ⚠ Undergraduate research conferences exist, including institutional symposia and the Florida Undergraduate Research Conference, and presenting is a substantial advantage for graduate applications.
Career Pathways
- ⚠⚠ This is the most employability-relevant course in a psychology degree, and it is worth stating bluntly because students consistently underrate it. Psychology is a very large undergraduate major with comparatively few psychology-specific jobs at bachelor's level. What differentiates graduates is methodological and statistical competence — and this course is where it is acquired.
- Psychologist (SOC 19-3033, 19-3039) — ⚠ requires a doctorate for clinical practice and licensure; this course and its grade are among the things graduate admissions committees look at most closely, and research experience beyond it is close to required for funded programmes.
- ⚠⚠ Market Research Analyst (SOC 13-1161) and Survey Researcher (SOC 19-3022) — arguably the most direct bachelor's-level destination for this skill set, and the work is experimental design and analysis under another name.
- Data Analyst and Data Scientist (SOC 15-2051) — ⚠ psychology graduates who can use R, understand experimental design and explain a confound are competitive here; A/B testing in industry is exactly this course's content.
- User Experience Researcher — ⚠ a real and growing field that hires psychology graduates specifically for methods training, and one most psychology students have never heard of.
- Program Evaluator and Social Science Research Assistant (SOC 19-4061) — in government, non-profits, health systems and universities.
- Human Resources and Training and Development (SOC 13-1071, 13-1151); Industrial-Organizational Psychologist (SOC 19-3032) with graduate study — ⚠ one of the better-paid applied psychology routes.
- Clinical research coordinator — ⚠ a substantial Florida category given the state's hospital systems and clinical-trial activity, and it hires for methods and regulatory literacy.
- Florida context: the state universities' research centres; large hospital systems (AdventHealth, Orlando Health, BayCare, Tampa General, UF Health) and their research offices; clinical research organisations; market-research and agency work in Miami, Orlando and Tampa; the Department of Health and Agency for Health Care Administration; and the theme parks and cruise lines, which run substantial consumer-research operations.
- ⚠ The honest framing: a psychology bachelor's plus this course plus R plus a statistics course is a genuinely marketable combination. A psychology bachelor's without them is not. The difference is a choice a student makes in their second year.
Special Information
⚠⚠⚠ Read this before registering: the number is doing three different jobs
Florida numbers research methods in psychology at least EIGHT ways, and `PSY3215` sits in a crowded and overlapping field:
| Number | Statewide title | Level | Statewide prerequisite |
|---|
PSY2210 | Research Methods in Psychology | lower | PSY2012 (C) and ENC1101 (C) |
⚠⚠ PSY3211 | ⚠⚠ Research Methods and Data Analysis in Psychology | upper | a statistics course |
PSY3213 | Foundations of Research Methodology | upper | general psychology and statistics |
PSY3215 | Principles of Research Methodology (CONT) | upper | — (but "(Cont)" implies one) |
PSY3017 | Experimental Psychology | upper | PSY2012 (C) and STA2023 |
PSY3234 | Principles of Inferential Methods | upper | — |
PSY4320 | Survey Methods in Psychology | upper | — |
PSY6214, PSY6216, PSY6217 | Principles / Advanced Research Methodology | graduate | — |
⚠⚠⚠ 1. FIU's title belongs to `PSY3211` — a misfiling
FIU calls this course "Research Methods and Data Analysis in Psychology", which is the statewide title of `PSY3211` — a separate number whose statewide prerequisite is a statistics course, and whose scope (methods plus data analysis) matches FIU's 4-credit value exactly.
⚠ So FIU appears to be running under `PSY3215` a course the state numbers `PSY3211`. The consequence is a transfer one: a student transferring FIU's `PSY3215` may find a receiving institution matching it against the statewide "(Cont)" definition — a second, advanced methods course — when what they actually took was the combined methods-and-analysis course. ⚠⚠ Or the reverse: a student who took a genuine second methods course elsewhere may be credited with FIU's combined course.
⚠⚠ 2. "(Cont)" says second course; UWF's title says first
The statewide marker "(Cont)" means a continuation, and the description says "complex research projects" — the vocabulary of a second course building on a first. ⚠ UWF's "Research Methods in Psychological Science" reads as a standalone first methods course.
⚠⚠ Why this matters practically: what the course ASSUMES differs. A genuine second methods course assumes you already know basic design, validity and t-tests, and spends its time on factorial designs, interactions and complex analysis. A first methods course teaches those basics. ⚠ A student who transfers in expecting the basics and meets a course that assumes them is in trouble by week three.
⚠ 3. And the credits diverge: FIU 4, UWF 3
⚠ Consistent with the above: FIU's extra credit reflects data analysis folded in; UWF's 3 credits is a methods course with statistics taken separately. ⚠⚠ Note also that the state flags this number as a LABORATORY course while neither carrier uses an `L` suffix — consistent with a methods course that includes scheduled laboratory or computer sessions inside its hours, and with FIU's fourth credit.
⚠⚠ What to actually do
- ⚠ Before registering, ask the psychology department two questions: is this the first or the second research methods course in the major, and is statistics a prerequisite, a corequisite, or built in? Those two answers identify which of the three readings you are getting.
- ⚠⚠ Before transferring, send the syllabus to the receiving psychology department — not the registrar. Psychology departments care what designs and analyses were covered, and the syllabus answers it where the number does not.
- ⚠ Keep the syllabus and your project report. For graduate applications the project is evidence of research competence, and the syllabus establishes the level.
Offering Notes — offerings and hours, school by school
| Institution | Its title | Credits | Contact hours |
|---|
| Florida International University | Research Methods and Data Analysis in Psychology | 4 | not published |
| University of West Florida | Research Methods in Psychological Science | 3 | not published |
⚠ Only two public carriers, both State University System, ⚠⚠ and they differ on credits, on title, and on which position in the sequence the number occupies. The statewide record also shows one private institution carrying it as "Research Methods II" — ⚠ which is the reading that matches the statewide "(Cont)" marker most closely, and is not listed above under the public-institution scope rule.
⚠ The 45 contact hours at the top of this guide are derived — the Florida convention for a 3-credit course, matching UWF's value. No institution publishes an hour figure. ⚠⚠ For FIU's 4-credit version expect about 60, consistent with a scheduled laboratory or computer session. ⚠ And treat either figure as understating the load: the course project is the real commitment — designing a study, obtaining IRB approval, collecting data, analysing it and writing it up in APA style is not classroom work.
⚠⚠ Prerequisites: what is stated, and what is actually required
No statewide prerequisite is listed for this number — ⚠ which, given the "(Cont)" marker, is almost certainly an omission rather than an intention. The sibling numbers show what is normally required:
- Introductory psychology (`PSY2012`), usually with a minimum grade.
- ⚠⚠ STATISTICS — and this is the one that matters. `PSY3211`, `PSY3213` and `PSY3017` all require it explicitly (`STA2023`, `STA2122`, `STA3111` or a psychological statistics course). Whether it is a prerequisite, a corequisite or folded in is the single most useful thing to establish about your section.
- First-year composition (`ENC1101`) at the lower-division sibling — because the course is a writing course as much as a design course.
- ⚠ A prior methods course, if your institution treats this number as the continuation the state says it is.
⚠⚠⚠ Name what is actually needed, because the statistics gap is where students fail: descriptive statistics, the normal distribution, sampling distributions and the standard error, the logic of hypothesis testing, t-tests and one-way ANOVA. ⚠ If your statistics course was a term ago and felt like a hurdle, revisit the logic of the sampling distribution before this course starts — everything in it rests on that one idea, and students who never grasped it cannot interpret an interaction.
⚠⚠ The replication crisis is not an optional topic, and a current course must cover it
⚠ Between roughly 2011 and 2015 psychology discovered that a large fraction of its published findings did not replicate, including several textbook results. The causes were methodological and incentive-driven rather than fraudulent: small samples, flexible analysis, selective reporting, and a publication system that rewarded surprising positive results.
⚠⚠ Why this belongs in a methods course rather than a history lecture: every technique the course teaches is now taught differently because of it.
| Before | Now |
|---|
| Report p < .05 and conclude | ⚠ report effect size and confidence interval; a p-value alone is not a finding |
| Collect a convenient sample | ⚠ power analysis first — decide the sample size before collecting |
| Explore the data, report what worked | ⚠⚠ preregister the hypothesis and analysis; label exploratory analysis as exploratory |
| Keep materials and data private | open data and materials as the default |
| A single significant study is evidence | replication and meta-analysis are evidence |
⚠ A course that teaches only the pre-2011 framework is teaching something the field has revised. ⚠⚠ The syllabus test: look for preregistration, power analysis, effect sizes and the word "replication." If they are absent, read the three papers named in the resources section yourself — they are short, free, and they are the reason the field looks as it does.
⚠⚠ The IRB will decide whether your project happens — start in week one
⚠⚠⚠ This is the most common practical failure in a methods course, and it is entirely avoidable. Any study involving human participants needs Institutional Review Board review, and approval takes time — days for an exempt determination at a well-run office, weeks if the protocol needs revision or if the population is vulnerable.
So, in week one: ⚠ find out how your institution handles STUDENT research (many have a streamlined class-project route, and some course projects are covered by a blanket protocol); complete CITI training if required, because it takes a few hours and blocks submission; find out the participant pool's rules and how to book it; and ⚠ ask the instructor what the realistic deadline is for having approval in hand.
⚠ Students who leave IRB to the midpoint of the term routinely end up analysing data they did not collect, or running a study too small to detect anything. Neither is a good outcome, and both are scheduling failures rather than intellectual ones.
Position in the curriculum, workload and the failure mode
A 3000-level course, ⚠ required in essentially every psychology major, and normally taken in the second or third year. Take it as early as the sequence allows — it is the prerequisite for meaningful involvement in a faculty member's laboratory, and ⚠ undergraduate research experience is what makes a graduate application competitive.
Budget ten to twelve hours a week, and ⚠ expect it to be badly distributed: moderate early, then dominated by the project. Data collection cannot be compressed, and that is what makes this course unforgiving of a late start.
⚠⚠⚠ The characteristic failure in this course is not statistical. It is claiming more than the design supports. Students run a correlational study and write that one variable affects another; they find a non-significant result and conclude there is no effect; they find an interaction and describe only the main effects.
⚠ The discipline is narrower and harder than it sounds: say exactly what your design licenses you to say, and no more. "These variables were associated; this design cannot establish direction" is a stronger sentence than a causal claim the study cannot support — and it is the sentence that distinguishes someone who understands methods from someone who has learned the vocabulary.
⚠⚠ The second failure is reporting a non-significant result as evidence of no effect. Absence of significance in an underpowered study is absence of information, and saying so honestly — with the power analysis to show it — is the correct and higher-scoring move.
AI Integration
⚠⚠ This course has an unusually pointed relationship with these tools, for two reasons: statistical analysis is exactly the kind of task they appear to do well, and the course's own subject is how to tell whether a claim is supported.
Genuinely useful: explaining a concept a second and third way — interactions, the sampling distribution, power and what a p-value means are the classic sticking points; explaining which test suits a design and why; writing and debugging R, SPSS syntax or jamovi steps — ⚠ a real and legitimate use, and R help is where it saves the most time; explaining what an output table means once you have produced it; generating practice design scenarios and asking you to identify the confound; helping structure an APA report; and checking APA formatting.
⚠ One genuinely strong use, well matched to the course: ask it to critique YOUR design. "What confounds does this study have? What would a reviewer object to?" is exactly what the course wants you to be able to do, and generating the objections to argue against is a good use of the tool.
⚠⚠ Where it fails, and the first three show up directly on graded work:
- ⚠⚠ It makes real errors in statistical reasoning while sounding authoritative. Which test is appropriate, whether an assumption is violated, how to interpret a three-way interaction, what a non-significant interaction licenses — these are exactly the judgements it gets subtly wrong. ⚠ And the tell is not obvious, because the prose is confident and the terminology is correct.
- ⚠⚠⚠ It fabricates statistical output, references and data. ⚠ And in this course fabricating data is the cardinal offence — more serious than plagiarism, because it attacks the basis of the discipline. Invented citations are also unusually easy to spot in psychology, because the field's literature is well indexed: an instructor can check an author-year in seconds.
- ⚠⚠⚠ And the deepest coincidence, which belongs on the syllabus: this course teaches you to ask whether a confident claim is supported by evidence, and the tool produces confident claims with no evidence at all. A generated statement about a psychological finding has no sample, no design, no effect size and no citation you can check — it is the exact epistemic object the course trains you to reject. ⚠ Running its output through the course's own checklist is a legitimately good exercise.
- ⚠⚠ It reproduces findings that did not replicate. Trained on decades of text including the pre-2011 literature and its popularisations, it will state ego depletion, priming effects, power posing and the facial-feedback hypothesis as established. ⚠⚠⚠ Those are precisely the replication-crisis examples this course covers — so the tool is a live demonstration of publication bias propagating, which is a better teaching example than any textbook figure.
- ⚠ NEVER put participant data into an AI tool. Your IRB protocol and consent form specify how data is stored and who sees it, ⚠ and pasting a dataset into a chat interface is a protocol violation as well as a confidentiality breach. De-identification is not sufficient if the protocol did not authorise it.
- ⚠ It cannot design a study for your context — your participant pool, your constraints, your ethical situation — and a plausible generic protocol will not survive IRB review.
⚠ The framing worth keeping: a researcher's authority rests on a traceable chain from data to claim. Anything you cannot trace, you cannot assert — which is both the answer to the fabrication problem and the whole content of this course. Use these tools to understand and to write code; own every number and every citation.
Academic integrity: read your syllabus, and expect a psychology department's policy to be explicit. ⚠ Where the assessment is an empirical report on data you collected, the data and the interpretation are the graded work, and an instructor who approved the protocol knows what your study could have produced.
